CIS REFUNDS UK

The Complete Contractor’s Guide to Getting Your Money Back from HMRC Fast

Valentis Accountants • 10 min read

If You’re Here… Chances are, you’ve stared at your bank statement thinking, “Why’s there always less money than the job said?”

Maybe you’ve worked your backside off on a site—packing up tools late, chasing invoices, haggling with suppliers—only to have HMRC play keep-away with the cash you’ve earned. CIS: It’s the world’s most convoluted savings account you never asked for. This isn’t the HMRC help page, and it’s not a dry accounting lecture. This is advice forged on deadlines, dirty overalls, and real-life headaches.

CIS in Plain Language

The Construction Industry Scheme (“CIS”) is HMRC’s way of nicking a chunk of your money before you even see it. You do a job, send an invoice, and rather than your full pay, some of your money—20%, or even 30% if you’re not registered—heads straight to the tax man.

Imagine CIS as that mate who insists on “holding onto your wallet for safekeeping,” swears they’ll return every penny, but you have to fill out three forms and nag them for weeks to see it again.

It’s not VAT. Don’t get twisted up. CIS is about labour, VAT is about goods and services. Keep your ledgers separate.
You may get it back—if you file correctly and don’t tick off HMRC.
It’s not your final tax bill, just what HMRC thinks you might owe. File, prove, reconcile, and you’ll sort out the true numbers.

Why Most People Get CIS Wrong

Myth #1

“Once HMRC takes the money, you’ll never see it again.”

Not true. CIS refunds go out every day—but only for those who’ve kept paperwork tidy and submitted the right stuff.

Myth #2

“You can fudge a few details. HMRC won’t notice.”

They will. And their software likes to find cock-ups. A single pound off, a missing statement, and your payment sits in limbo.

Myth #3

“You’ll only get paid back at year-end.”

Companies can offset CIS against PAYE each payroll month—don’t wait till April to sort mistakes. Sole traders, yes, you need to file Self-Assessment, then wait for the return.

Who Actually Gets CIS Refunds?

Sole Traders & Partnerships

You’re a one-man band, or you and a mate split everything—even the tax headaches. You file for a refund using your Self-Assessment tax return. Keep every Payment and Deduction Statement from every contractor who’s paid you.

If the CIS tax taken exceeds your tax bill, you get the extra back—or HMRC sets it against other debts.

Limited Companies

You’re incorporated. CIS deductions for companies are tracked through PAYE returns. Every month, add your cumulative CIS deductions to the Employer Payment Summary (EPS).

At tax year-end, claim refunds if the CIS tax withheld outweighs your PAYE and NIC liabilities.

Multi-Role Businesses

You hire subs, you also get hired. It’s double the admin, sorry. You track deductions you make (as a contractor) and deductions you suffer (as a subbie). The two pots never mix—different processes, timelines, and paperwork.

Real Story

Dave’s a groundworker in Leeds. He’s got three regular contractors. One lost a CIS statement in February. Instead of “hoping it turns up,” Dave calls, gets a replacement, and files every slip, neat as a pin. Refund processed in 3 weeks. His mate, who didn’t follow up, waited 4 months.

Claiming Process, Step-by-Step

A. Sole Traders & Partners

1
Keep the Paper Trail — Monthly PDS from each contractor, spreadsheet reconciling to the penny
2
File Self-Assessment — Enter total CIS tax deducted, gross income, and allowed expenses in precise figures
3
Track Your Filing — Save computation, confirmation, and receipts
4
Refund or Offset — If you owe nothing else, money arrives to your bank. Have overdue tax? HMRC knocks that off first
5
Respond Promptly — If HMRC wants proof, send detailed reconciliations in one document

B. Limited Companies: The Payroll Route

1
Monthly EPS Entry — Must show total CIS suffered since April. Missed months = slow refunds
2
Year-End Reconciliation — Run numbers before final FPS/EPS. Get every statement
3
Final Submission and Claim — File last FPS/EPS. Request refund with all docs
4
Proactive Response — Bundle all statements, contractor by contractor, with index and summary
5
Track Everything — Diary dates you file, chase up, and reply to HMRC

Real Story

Sarah owns a small electrical business. For two months, she didn’t enter any EPS. At the end of the year, her CIS refund was put on hold. It took two hours to put together the ledgers again, and two more months to get the money back. Lesson: Even when you’re busy, update your payroll.

Smart Ways to Get Things Done Faster

Down the Pub: Contractor-to-Contractor Questions

“How fast did you get your last CIS refund?”

If your answer is “a month,” you did it right. “Six months?” Let’s talk about your paperwork.

“Does your accountant really know CIS?”

Some don’t. Always quiz them: have they fixed refunds for contractors in your trade before?

“Ever had HMRC hold your refund for ages?”

Yes—if EPS was off by a tenner, or paperwork was messy. Tidy up and chase them weekly.

“Is it better to be a sole trader or an Ltd company for CIS?”

It depends, mate. Sole traders get paid quicker, Ltd companies get options for other offsets, but more admin.

Common Mistakes and the Pain They Cause

Claiming refunds in the wrong place: Sole traders use Self-Assessment, companies use EPS. Never use a Corporation Tax return for CIS!
EPS/PDS mismatch: Amounts on Employer Payment Summary not matching Payment and Deduction Statements stop HMRC cold. Fix before filing.
Missing Statements: Invoices aren’t enough. Need the right CIS paperwork to prove deduction.
Confusing CIS and VAT: Reverse charge stuff spins heads. Keep VAT and CIS separate or expect sleepless nights.
Premature Filing: Don’t file before you’ve got all your statements—the fund will get stuck in HMRC’s system.
Letting bank details lapse: Refunds head to old accounts if details aren’t up to date. Change every time your banking changes.
Ignoring new basis rules (2023–2025): Basis period reform means some sole traders will see profits split differently for a couple of years—watch for transition hiccups.
Not checking both contractor and subbie records (if you do both): Separate files, separate ledger accounts—mix them and your accountant will hate you.

Ways to Speed Up

Respond same day to HMRC requests. Include all evidence in one tidy bundle. Keep reconciliation schedules short and easy to follow.

Q&A — Stuff No Accountant Will Admit Until Pressed

No, but if you don’t, contractors dock 30% instead of 20%, so you’re basically gifting HMRC a loan.

Never. Payroll route for companies, Self-Assessment for individuals.

Companies offset against PAYE as you go—means more cash, faster.

As far as statutory amendment windows (usually a couple of years). Late claims are harder and need more paperwork.

Every time. They’ll pay themselves before paying you.

Get missing statements in writing. Document every chase. If they won’t help, escalate to HMRC with your own evidence.

No—HMRC hates rounding and guesses. Give actual figures.

Staying On Top: Monthly and Annual Routine

OUR PROCESS

Valentis—the Crew That Makes CIS Refunds Easy

1

Onboarding

We map your contractors, chase formats and files, and clean up ledgers from the start.

2

Monthly housekeeping

We check every posting, reconcile CIS versus statements, file EPS/FPS, and track all admin.

3

Pre-year-end

Practice reconciliations means no panic at the deadline. We test, correct, and keep you compliant.

4

Final filings and claims

We do all the evidence packs, submit airtight claims, file early, and update you at every step.

5

Aftercare

If HMRC kicks up a fuss, we respond within days, not weeks. Offset issues, questions, and we sort them.

Real Example

Jenny, a company director, forgot her last EPS. We spotted it, fixed the numbers, and filed the corrected claim. HMRC accepted and paid the refund two weeks later.

Real Example

Tom, a sole trader brickie, filed online with missing statements. HMRC froze his refund until we chased the contractor, got replacements, sent a bundle—money appeared next Friday.

The Stuff That Trips Up Most Contractors (and How to Dodge It)

Using old accountant spreadsheets that don’t match statement formats.
Forgetting mid-year rule changes (new contractor, new format? Get a sample and template first).
Not double-checking online submission receipts.
Never labelling PDF bundles properly—“scan.jpg” isn’t good enough!
Treating amendments as “fix it next year”—better to fix today, faster cash.
Ignoring diaries and reminders for chasing refunds—set phone alerts, not just paper ones.

Troubleshooting

No movement after filing

Check that you filed the right form, correct the HMRC service, and that all evidence was supplied.

Mismatch with HMRC?

Reconcile lines, explain with simple documents—not rambling emails.

Gross payment status risk?

Fix compliance, pay debts, let HMRC know you’re sorting it out.

Contractors refusing to send statements?

Record every request, keep delivery receipts, and compile all invoices.

Going Deeper—Specific Situations

Company Directors

Don’t assume your company CIS gets refunded automatically—track PAYE balances, and chase every missing month. Non-exec directors need a separate summary.

Multi-Trade Businesses

You might work in plumbing and bricklaying, have different rates and contractors. Keep statements by trade, file evidence by contractor and trade.

Disputed Payments

Contractor claims to have paid CIS, but the statement’s missing. Chase firm and HMRC, provide alternate proof if necessary.

Human Stories: When It Works, When It Doesn’t

Steve’s Story

Steve’s an old-school sparky, likes things on paper. Missed two CIS statements and forgot his EPS entry. With a little pressure from Valentis, he sorted the paperwork, and HMRC paid his refund with interest for the delay.

Julie’s Example

Julie runs a landscaping crew. She kept every statement, cross-referenced every payment, and sent the neatest evidence bundle HMRC ever saw. The refund was in her account before the trade show even started.

Final Thoughts: Get Your Money, Keep Your Sanity

There’s nothing magical about CIS refunds. You just need to out-organise HMRC, outpace contractor admin, and stay ahead of their questions. The more human, real-world your submission—clearly labelled, logically matched, and packed as if for someone who’s busy—the faster you’ll see your cash.

Work with accounting partners who actually know the trades, who will fight your corner, and who won’t let HMRC stall for months. Valentis gets it done because we care how business works outside an office. You work hard—make sure your refund shows up just as fast.

Ready to get started, or pissed off at HMRC for another sluggish refund? Reach out now, and let’s sort it before the cash dries up. The sooner it’s sorted, the sooner you’re back in control.
